Hypocalcemia In Chronic Kidney Disease

Hypocalcemia In Chronic Kidney DiseaseKidney plays multiple role in our life activity, so when kidneys shut down, various health issues will be caused. Hypocalcemia is a common electrolyte imbalance among Chronic Kidney Disease (CKD) patients, so having an overall understanding about it is very necessary.

What is hypocalcemia?

Normally, calcium level in blood fluctuates in the range of 2.2-2.7mmol/L or 8.8-10.4mg/dl. Hypocalcemia refers to low calcium level in blood, which is diagnosed when calcium level in blood is lower than 2.2. This kind of health issue is always accompanied with a series of bone discomforts like bone pain, bone weakness and osteoporosis. Mild hypocalcemia can be alleviated or cured with diet changes, but for severe hypocalcemia, medical treatment is needed.

How is hypocalcemia caused in Chronic Kidney Disease?

In Chronic Kidney Disease, appearance of hypocalcemia mainly results from the following three conditions:

1. Phosphorus and calcium metabolism disorders

One of the major jobs of kidney is to keep electrolyte balance, so when kidneys fail to function properly, electrolyte imbalance is caused. Damaged kidneys can not remove excess phosphorus out of the body, leading to hyperphosphatemia. In our body, the concentration of calcium and phosphorus is kept in a relatively stable level. When there is too much phosphorus level in blood, the concentration of calcium level decreases.

2. Metabolic disturbance of vitamin D

In Chronic Kidney Disease, due to impaired kidney function, phosphorus level in blood increases, which inhibit the production of 1.25(OH)2D3. This substance plays an important role for our body to absorb necessary calcium, so when the production of it is inhibited, calcium level in blood decreases. This plays a part for hypocalcemia in Chronic Kidney Disease.

3. Strict diet limitation

Diet changes are needed with diagnosis of Chronic Kidney Disease, because improper diet will aggravate illness progression. In general, to bring illness under control, CKD sufferers have to stay far away from many foods, which may stop sufferers from getting enough calcium. Therefore, strict diet plan also plays a part for the appearance of hypocalcemia in Chronic Kidney Disease.

Hypocalcemia is one of the most common electrolyte disturbances in Chronic Kidney Disease. Besides it, there are many others like hypernatronemia, hyperkalemia and hyperphosphatemia. If you have any questions about these problems, please leave us message or contact online doctor.
